Are these Britney Spears' measurements? A body double ad says so

Britney Spears is busy preparing for her
"Piece of Me" Planet Hollywood residency in Las Vegas. And while one might think that means hardcore choreography and dance rehearsals, vocal calisthenics and a diet of lean proteins and greens, it could actually mean just hiring a body double to do some of the dirty work for her.

Hollywood Life came across a casting notice that gives away Spears' exact weight, height, body measurements, and shoe and dress sizes. "
Looking for a body double for Britney Spears," the ad reads. "Please only submit if you have these measurements or are very close to them all." The casting agent is looking for someone with a 32C bra size, which seems like an awfully narrow measurement for our broad-shouldered Britney. A weight of 130 lbs. and dress size 4 sound about right. As for the 27-inch waist and 35-inch hips, we'll let you be the judge.

Brit was previously
accused of using a dance double for her 2011 "Hold It Against Me" video when she couldn't keep up with the complicated choreography, but her reps denied it at the time. The jury's still out on whether a backup dancer filled in for Spears in her "Till the World Ends" video, but the
photo evidence is a bit tough to refute.
